The warning follows a recent Facebook post that went viral. The images, shared by a veterinary nurse, shows the damage grit can do to our dogs.
In this case, grit had peeled away one of the dog's paw pads, leaving the little Chihuahua with a very painful looking injury.
The RSPCA issues important warning to dog owners
But that's not the only concern for owners and their dogs. We all know that dogs have an "eat it now and see what happens later" approach to food. However, gritting salt is potentially toxic to dogs and may cause serious health problems if ingested.
The RSPCA reminded owners to keep a careful eye on curious pooches during winter walkies and take extra precautions when they get back in from the cold.
When to call a vet for your pooch
The animal rescue service also advised fur parents to immediately contact a vet if they suspect a dog has eaten rock salt or grit.
